=OPS635 Lab 3: System Configuration Management using Ansible=
==Overview==
In an enterprise environment, the existence of different hardware and operating systems running on production servers is very common. You may find the same software running on different OSes and even different hardware platforms. To manage the software configuration on different platforms by using a script, your script would have to be aware of and account for their differences. Your scripts would need to be written in way that they know how to query the operating environment and execute the appropriate installation and configuration actions based on the operating environment it is running on.
**The firewall-cmd service is running and enabled.
**Firewalld is not allowing the mdns or cockpit services. Remember to also make this permanent.
*Use the terminal on the client to confirm these changes worked.
*While these changes are not important to the service you will configure using a playbook in the next investigation, they give you some experience using one-off commands in ansible.
